s Orbitals
s
Orbitals are spherically symmetric.
The energy of an
s orbital increases with the
number of nodal surfaces it has.
number of nodal surfaces it has.
A nodal surface
is a region where the probability
of finding an electron is zero.
of finding an electron is zero.
A 1s
orbital has no nodes; a 2s
orbital has one;
a 3s orbital has two, etc.
a 3s orbital has two, etc.
